SPRINKLING DEVICE.

Specification of Letters IPatent.

Patented June 21, 1910.

Application filed July 10, 1909. Serial No. 506,973.

pertains to make and usethe same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in sprinkling apparatus especially adapted for street sprinkling and irrigating purposes and comprises various details of construction and combinations and arrangements of parts which will be hereinafter fully described and then specifically defined in the appended claim.

I illustrate my invention in the accom panying drawings, in which Figure 1 is a perspective view showing the sprinkling system as applied to intersecting streets. Fig. 2 is an enlarged detail view in elevation, and Fig. 3 is an enlarged detail sectional view.

lxeference now being had to the details of the drawings by letter, A and A designate intersecting streets upon which are the double tracks B of the car line and positioned along the tracks adjacent to the edges there.- of are embedded water mains D, one of which is shown in Fig. 2 of the drawings in which main a union F is shown and to which is connected a pipe E, forming a por-' tion of one of the sprinkler heads. Each of said sprinkler heads has a cap I with overhanging edges C, said cap being recessed as at 1 upon its under surface to receive the upper contracted end H of the shell H telescoping within the pipe E and held to the cap y means of a screw IF, the under surface of said cap about its recess resting upon the annular shoulder H? formed upon said shell. \Vhen the cap is in its normal position, it is supported by the upper end of the pipe E. Said shell has a flange H at its lower end, the outer end of which flares and is adapted to contact with the lower end of the pipe E to limit the movement of the sprinkler head. The circumference of the upper portion' of the shell is provided with an annular enlargement H in contacting relation with the inner surface of the pipe and has perforations K therein, while a slight space intervenes between the shell below said annular enlargement and the inner surface of the tube, said perforations being so located that,

when the pressure "of the water coming against the inner end of the head raises the latter, the perforations-will be positioned above the end of the pipe E and will throw the water radially in different directions. The sprinkling will continue until the weight of the sprinkler head overcomes the pressure of the water, at which moment the head will fall so that the cap will rest 11 on the upper endofthe pipe. When the ead is in a closed position, the foreign matter will be prevented from entering the perforations and the head will be so positioned that it will not ofler an obstruction extending above the surface of the ground to any appreciable ext nt.

that I claim to be new is i In combination with an open ended vertically disposed. pipe, a tubular shell telescoping therein and havingits lower end flaring and of greater diameter than the pipe within which it telescopes and cooperating therewith to limit the upward throw of the shell, the upper portion of the shell being contracted and provided with an annular shoulder about its contracted portion, the up er portion of the shell being circumferentia ly perforated, and provided with an annular enlargement in contacting relation with the inner surface of the pipe, a cap having a recess in its under face in which the upper contracted end of the shell is seated, the under surface of the cap about said recess resting upon said annular shoulder and adapted to seat on the upper end of the ipe, and a screw passing through the top of the shell and cap. i

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.

JOHN FRANKLIN SMITH.
